To a solution of (R)-6-(3-aminopiperidin-1-yl)-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide (27.5 mg, 0.065 mmol) and Et3N (0.014 mL, 0.097 mmol) in THF (2 mL) was added benzoyl chloride (10.93 mg, 0.078 mmol). The reaction mixture was stirred at rt for 10 min, quenched with satd. NaHCO3, extracted twice with CH2Cl2, separated, and concentrated. The residue was purified by ISCO (100% ethyl acetate, 12 g column) to obtain 24 mg of (R)-6-(3-benzamidopiperidin-1-yl)-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide as a white solid. LCMS: (M+H)+=529.38. 1H NMR (400 MHz, CDCl3) δ ppm 11.22 (1H, s), 7.66 (2H, d, J=8.56 Hz), 7.59-7.64 (2H, m), 7.53 (1H, d, J=9.06 Hz), 7.42-7.49 (1H, m), 7.37 (1H, d, J=7.81 Hz), 7.31 (1H, d, J=8.56 Hz), 6.55 (1H, d, J=6.80 Hz), 6.11-6.18 (1H, m), 5.60 (2H, s), 4.17-4.28 (1H, m), 3.86-3.94 (1H, m), 3.53-3.83 (11H, m), 1.96-2.06 (1H, m), 1.88-1.95 (1H, m), 1.74-1.85 (1H, m), 1.67-1.73 (1H, m).
